ALBERT 0. BUCKIUS, JR., OF CHICAGO, MALLEABLE CASTINGS COM METHOD OF MAKING JOURNAL-BOXES.

Specification 0 To all whom it may concern.

Be it known that I, ALBERT O. Buoxios, J r., a citizen of the United States, residing at Chicago, Cook county, State of Illinois, have invented new and useful Improvements in Methods of Making Journal-Boxes, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 shows an elevation of a journal box constructed in accordance with my invention; Fig. 2 is a top plan view thereof; Fig. 3 is a section thereof; Fig. 4 is a section on linesIV-IV of Fig. 2; Fig. 5 shows a section of a modified form of my invention, taken along the line VV of Fig. 6, and Fig. 6 is an elevation thereof.

My invention relates to journal boxes of that type in which the top is made of cast metal and the bottom or oil cellar is made of pressed or rolled metal. My invention consists in the method of securing together the parts of the box.

Referring to the drawings, A indicates the top of the box, preferably made of cast steel because of its complex shape, and B the bottom or oil cellar, preferably made of pressed steel. The oil cellar B has upon the top of its sides a number of upwardly-extending lugs or projections 2, and the top A has a plurality of slots 3, which flare upwardly and outwardly, and through which the projections 2 are designed to extend. The dust guard 4. may be made integral with the cellar B, but is preferably secured thereto by spot welding.

In securing the parts together, the projections 2 of the bottom B may be heated red hot, the top A placed in position on the bottom with the projections 2 seated in the slots 3; the projections 2 may then be hammered down until they fill the V-shaped slots 3 and form a tight mechanical bond between the top A and collar B. As the projections cool they will shrink to some extent and still further make tight and secure the joint between the two parts. In Figs. 1, 2, 3 and 4 the projections 2 are in their original unswaged condition, while those marked 2 have been upset and form a dovetailed connection with the top A.

In Figs. 5 and 6 I have shown a modifi- Gopies of this patent may be obtained for five cents each, by addressing the r Letters Patent. Patented June 12, 1917.

cation of my invention, in which the top A of the box is cast integral with a side frame C. In this form the oil cellar B may be secured to the top in the manner described above.

It is obvious that many changes may be made in the method which I have described for securing together the parts of the box, and in the box itself, without departing from my invention. For instance, the parts may be united by placing a Welding material in the slots around the projections, and then melting this material by the oxy-acetylene torch or any other well known process until it fuses with the projections and with the walls of the slots, thereby producing a .welded bond between the top and the bottom, as is shown in Figs. 5 and 6.

What I claim is:

1. The method of making a journal box which consists in forming the top of the box out of cast steel with a plurality of slots therein, applying the top of the box thus formed to a preformed part having a plurality of projections thereon, the metal of the projections being heated before assembly, and upset while heated to form with the slots an interlock between the bottom and top of the box.

2. The method of making a journal box which consists in fitting together preformed top and cellar portions having slot and projection engagements, the slots being flared outwardly, the projections being preheated, and thereafter interlocking the heated projections in the slots by pressing down their ends to substantially fill the slots.

3. The method of making a journal box which consists in separately preforming the top and bottom portions of the box, the top having a plurality of outwardly flaring slots and the bottom having projections of progressively less cross section than theslots, applying the top to the bottom with the projections in the slots, and then filling the slots with metal and thereby providing a dovetailed connection between the parts.
